Question 1Anatomy and Physiology of the Eye and Eyelashes

Which layer of the eyelash follicle is responsible for anchoring the hair shaft and providing the blood supply for growth?

  1. The cuticle of the hair shaft
  2. The sebaceous gland duct
  3. The orbicularis oculi muscle
  4. The dermal papilla at the base of the follicle Correct answer.

Explanation

The dermal papilla sits at the base of the follicle and contains capillaries that deliver nutrients to the dividing matrix cells, so it drives and sustains lash growth. It is also the structure that must not be damaged during lash work, since injury there disrupts regrowth.

Question 2Anatomy and Physiology of the Eye and Eyelashes

The average growth phase (anagen) of an upper eyelash follicle lasts approximately how long?

  1. One to two years
  2. One to two months Correct answer.
  3. One to two weeks
  4. Five to seven years

Explanation

Upper eyelash anagen is short compared with scalp hair, generally lasting about one to two months, which is why lashes stay short. The brief growth phase followed by catagen and telogen explains the natural shedding cycle every few weeks.

Question 3Anatomy and Physiology of the Eye and Eyelashes

Which structure produces the oily secretion that coats the eyelid margin and helps slow tear evaporation?

  1. The lacrimal gland
  2. The goblet cells of the conjunctiva
  3. The glands of Zeis
  4. The meibomian glands Correct answer.

Explanation

Meibomian glands are sebaceous glands embedded in the tarsal plates that secrete lipids onto the lid margin, forming the outer layer of the tear film. This lipid layer reduces evaporation and keeps tears stable on the ocular surface.

Question 4Anatomy and Physiology of the Eye and Eyelashes

A client has very sparse lashes and you notice tiny mites and cylindrical dandruff at the lash bases. Which condition should you recognize before proceeding?

  1. Blepharitis associated with Demodex infestation Correct answer.
  2. A stye caused by a blocked meibomian gland
  3. Pinguecula on the sclera
  4. Entropion of the lower lid

Explanation

Cylindrical dandruff at the lash roots combined with lash loss is a classic sign of Demodex mite infestation, which produces a form of blepharitis. This is a medical condition requiring referral rather than a cosmetic lash service.

Question 5Anatomy and Physiology of the Eye and Eyelashes

Which of the following best describes the function of the levator palpebrae superioris muscle?

  1. It raises the upper eyelid Correct answer.
  2. It constricts the pupil
  3. It rotates the eyeball downward
  4. It closes the eyelid during blinking

Explanation

The levator palpebrae superioris elevates the upper eyelid, keeping the eye open and controlling lid height. Its opposing muscle, the orbicularis oculi, closes the lid, and the two must stay balanced for normal eyelid position.

Question 6Anatomy and Physiology of the Eye and Eyelashes

The natural eyelashes are arranged in rows along the lid margin. Approximately how many rows of lashes grow on the upper eyelid?

  1. Two to three rows Correct answer.
  2. Five to six rows
  3. Eight to ten rows
  4. One to two rows

Explanation

Upper eyelid lashes typically grow in about two to three irregular rows along the anterior lid margin. Lower lashes are usually fewer and arranged in one to two rows, which is why upper lashes look fuller.

Question 7Anatomy and Physiology of the Eye and Eyelashes

Which part of the hair shaft is the tough outer layer of overlapping cells that protects the inner fibers?

  1. The cortex
  2. The medulla
  3. The cuticle Correct answer.
  4. The root bulb

Explanation

The cuticle is the outermost layer of the hair shaft, made of overlapping scale-like cells that shield the cortex beneath. Its condition affects how lashes respond to products, since a damaged cuticle looks rough and loses shine.

Question 8Anatomy and Physiology of the Eye and Eyelashes

Why should a technician avoid applying adhesive directly to the eyelid skin rather than the isolated natural lash?

  1. Adhesive on skin can bond lashes together and irritate the delicate lid surface Correct answer.
  2. Adhesive on skin makes extensions fall off faster
  3. Adhesive on skin changes the natural lash growth cycle
  4. Adhesive on skin prevents the eyes from blinking

Explanation

Eyelid skin is thin and sensitive, and cyanoacrylate adhesive applied to it can cause irritation, bonding of neighboring lashes, and discomfort. Correct isolation keeps adhesive on the lash shaft only, protecting both the skin and the lash line.

Question 9Anatomy and Physiology of the Eye and Eyelashes

During the telogen phase of the lash cycle, what happens to the hair?

  1. It rests and is eventually shed Correct answer.
  2. It becomes permanently attached to the follicle
  3. It darkens in color
  4. It grows rapidly and thickens

Explanation

Telogen is the resting phase in which growth stops and the lash remains in the follicle before being shed. A new anagen lash then begins to grow in its place, which is why natural shedding is part of a normal cycle.

Question 10Anatomy and Physiology of the Eye and Eyelashes

A client's natural lashes point sharply downward and cross the lower lid. What is the most appropriate professional response?

  1. Trim the offending lashes with scissors
  2. Apply extra-strong adhesive to force the lashes upward
  3. Refer the client for assessment of trichiasis before any lash service Correct answer.
  4. Proceed with a volume set using heavier extensions

Explanation

Downward-directed lashes rubbing the eye suggest trichiasis, an abnormal lash direction that can scratch the cornea and requires medical evaluation. A technician should not attempt to correct it cosmetically or cut lashes.

Question 11Anatomy and Physiology of the Eye and Eyelashes

Which statement accurately describes the difference between the upper and lower eyelash follicles?

  1. Lower lashes are typically longer and more numerous than upper lashes
  2. Lower lashes grow in more rows than upper lashes
  3. Upper lashes are typically longer and more numerous than lower lashes Correct answer.
  4. Upper and lower lashes are identical in length and count

Explanation

Upper eyelid lashes are generally longer, thicker, and more numerous, growing in about two to three rows. Lower lashes are shorter, sparser, and arranged in fewer rows, which is why upper lashes dominate the lash line visually.

Question 12Anatomy and Physiology of the Eye and Eyelashes

The tarsal plate gives the eyelid its shape and support. Where is it located?

  1. Along the outer corner of the eye only
  2. Within the eyelid, between the skin and the conjunctiva Correct answer.
  3. Inside the orbit behind the eyeball
  4. On the surface of the cornea

Explanation

Each eyelid contains a tarsal plate, a firm connective tissue layer that gives the lid structural support and houses the meibomian glands. It lies within the lid between the skin and the palpebral conjunctiva.

Question 13Anatomy and Physiology of the Eye and Eyelashes

A client reports that her eyes water constantly and feel gritty after lash application. Which anatomical structure's function is most likely being disrupted?

  1. The lens of the eye
  2. The optic nerve
  3. The ciliary body
  4. The meibomian gland lipid layer of the tear film Correct answer.

Explanation

Watery, gritty eyes after lash work often reflect disruption of the meibomian lipid layer, which allows tears to evaporate and triggers reflex tearing. Products or adhesive fumes near the lid margin can interfere with this oily layer.

Question 14Anatomy and Physiology of the Eye and Eyelashes

Which structure secretes the aqueous component of tears?

  1. The iris
  2. The lacrimal gland Correct answer.
  3. The tarsal plate
  4. The eyelash follicle

Explanation

The lacrimal gland, located in the upper outer orbit, produces the watery aqueous layer that makes up most of the tear film volume. This fluid washes the ocular surface and delivers oxygen and nutrients to the cornea.

Question 15Anatomy and Physiology of the Eye and Eyelashes

Why is understanding the direction of natural lash growth important when applying extensions?

  1. Growth direction only matters for lower lashes
  2. Growth direction determines the color of the extension
  3. Extensions should follow the natural growth direction to avoid pulling and discomfort Correct answer.
  4. Extensions should be applied opposite to growth direction for better hold

Explanation

Natural lashes grow outward and slightly upward, so extensions must be attached in that same orientation to sit comfortably and avoid twisting or traction on the follicle. Misaligned extensions create weight and pull that can damage lashes over time.

Question 16Anatomy and Physiology of the Eye and Eyelashes

Which of the following is a normal function of the orbicularis oculi muscle?

  1. Focusing the lens
  2. Producing sebum for the lid margin
  3. Closing the eyelids and pumping tears toward the drainage ducts Correct answer.
  4. Raising the upper eyelid

Explanation

The orbicularis oculi is a circular muscle that closes the eyelids during blinking and squeezing, and its contraction helps move tears toward the puncta and nasolacrimal duct. It works in opposition to the levator palpebrae superioris.

Question 17Anatomy and Physiology of the Eye and Eyelashes

A client has a visible red, tender lump at the base of one lash line. How should the technician proceed?

  1. Apply a warm compress and continue the full set
  2. Apply extensions around the lump and monitor it
  3. Pop the lump with a sterile tool
  4. Postpone the service and advise the client to seek medical advice Correct answer.

Explanation

A tender red lump at the lid margin may be a hordeolum (stye) or other infection, which is a contraindication for lash services because products and tools could spread infection or worsen inflammation. The client should be referred for medical assessment and the service postponed.

Question 18Anatomy and Physiology of the Eye and Eyelashes

Which layer of the hair shaft contains the melanin that gives lashes their color?

  1. The medulla
  2. The cuticle
  3. The cortex Correct answer.
  4. The inner root sheath

Explanation

Melanin pigment granules are deposited in the cortex, the thick middle layer of the hair shaft, which determines lash color. The cuticle is transparent and protective, while the medulla is a central core that may be absent in fine lashes.

Question 19Anatomy and Physiology of the Eye and Eyelashes

What is the primary role of the eyelashes in protecting the eye?

  1. They focus incoming light
  2. They produce tears
  3. They deflect debris and trigger a blink reflex when touched Correct answer.
  4. They sense light intensity

Explanation

Eyelashes act as a first line of defense, catching dust and particles and triggering the blink reflex when something touches them. This protects the cornea and conjunctiva from injury and drying.

Question 20Anatomy and Physiology of the Eye and Eyelashes

A client's lashes appear thin and break easily, with a rough surface. Which structural change best explains this appearance?

  1. Increased melanin in the medulla
  2. Overgrowth of the tarsal plate
  3. Damage to the cuticle layer of the hair shaft Correct answer.
  4. Swelling of the lacrimal gland

Explanation

The cuticle is the protective outer layer of the shaft; when it is damaged, the underlying fibers are exposed and the lash looks rough, weak, and prone to breakage. Gentle handling and avoiding harsh products help preserve cuticle integrity.

Question 21Anatomy and Physiology of the Eye and Eyelashes

Which sequence correctly describes the order of the hair growth cycle for an eyelash?

  1. Anagen, catagen, telogen Correct answer.
  2. Catagen, telogen, anagen
  3. Telogen, anagen, catagen
  4. Anagen, telogen, catagen

Explanation

A lash follicle cycles through anagen (active growth), catagen (transition and regression), and telogen (rest before shedding). After telogen the lash is shed and a new anagen cycle begins.

Question 22Anatomy and Physiology of the Eye and Eyelashes

A technician notices that a client's extensions are twisting and pulling at the natural lash base after a week. Which factor most likely contributed?

  1. The natural lash was in telogen
  2. The extension was attached without following the natural lash direction and base alignment Correct answer.
  3. The extension was too light for the lash
  4. The client used too little adhesive remover

Explanation

Twisting and traction usually result from poor alignment, where the extension base is not matched to the natural lash direction and the bond sits off-center. Correct isolation and base placement distribute weight evenly and prevent pulling.

Question 23Anatomy and Physiology of the Eye and Eyelashes

Why does the upper eyelid margin carry more meibomian gland openings than the lower eyelid margin in most people?

  1. The upper lid has no sebaceous glands at all
  2. The lower lid lacks a tarsal plate
  3. The upper tarsal plate is larger and houses more meibomian glands Correct answer.
  4. The lower lid glands secrete only mucin

Explanation

The upper tarsal plate is taller and contains a greater number of meibomian glands, so more openings appear along the upper lid margin. These glands supply the lipid layer that stabilizes the tear film across the ocular surface.

Question 24Anatomy and Physiology of the Eye and Eyelashes

A client repeatedly rubs her eyes and has lost several natural lashes over a short period. Which interpretation is most accurate?

  1. The client must have a bacterial infection
  2. The lashes will never regrow after rubbing
  3. Mechanical rubbing may be causing traction alopecia of the lashes and should be addressed Correct answer.
  4. This is normal telogen shedding and requires no comment

Explanation

Repeated rubbing creates mechanical trauma that can pull lashes from the follicle, a form of traction loss that may reduce density over time. Advising the client to avoid rubbing and referring persistent cases supports follicle recovery.

Question 25Anatomy and Physiology of the Eye and Eyelashes

Which anatomical relationship explains why adhesive fumes near the lid margin can cause watering and irritation?

  1. The lid margin is connected directly to the lacrimal sac without any barrier
  2. The lid margin has no nerve endings
  3. The lid margin is close to the ocular surface and its tear film, which reacts to volatile compounds Correct answer.
  4. The lid margin contains the optic nerve

Explanation

The lid margin borders the conjunctiva and tear film, so volatile adhesive compounds can dissolve into tears and stimulate the richly innervated ocular surface. This proximity is why ventilation, curing, and careful placement matter during application.

Question 26Anatomy and Physiology of the Eye and Eyelashes

The eyelash follicle is anchored in the dermis of the eyelid. Which structure surrounds the upper portion of the follicle and is thought to contribute to the lash's sensitivity and blood supply?

  1. The tarsal plate
  2. The hair bulb matrix
  3. The sebaceous gland Correct answer.
  4. The conjunctiva

Explanation

Sebaceous glands (glands of Zeis) are attached to the upper part of the eyelash follicle and secrete sebum that coats the lash shaft. They are part of the pilosebaceous unit and are distinct from the meibomian glands embedded in the tarsal plate. The hair bulb matrix is at the base of the follicle and produces the hair shaft, not a surrounding gland.

Question 27Anatomy and Physiology of the Eye and Eyelashes

A client's natural lashes are in the catagen phase. What is the most accurate description of what is happening to the lash at this stage?

  1. The lash has fallen out and the follicle is resting.
  2. The lash is actively growing and lengthening.
  3. The lash has stopped growing and the follicle is shrinking. Correct answer.
  4. The lash is shedding because a new lash is pushing it out.

Explanation

Catagen is the transitional phase of the lash cycle, lasting a few weeks, during which growth stops and the follicle begins to regress. The lash remains in place but is no longer lengthening. Shedding occurs later, in telogen, when the hair is pushed out by a new anagen lash.

Question 28Anatomy and Physiology of the Eye and Eyelashes

A client has very straight, downward-pointing upper lashes. When selecting extensions, why should the technician choose a curl that complements rather than sharply opposes the natural direction?

  1. A curl that opposes the natural direction will slow the natural lash growth cycle.
  2. A curl that matches the natural direction will make the extensions appear longer.
  3. A stronger curl always reduces the weight of the extension on the natural lash.
  4. A curl that opposes the natural direction can cause the extension to lift away from the natural lash and twist. Correct answer.

Explanation

The extension should follow the natural lash's growth direction so that the bond sits correctly and the extension does not pull or rotate. If the curl fights the natural direction, the extension can lift at the base and twist, which may irritate the lid and reduce retention. Curl choice affects appearance and fit, not the length of the extension or the speed of the growth cycle.

Question 29Anatomy and Physiology of the Eye and Eyelashes

A technician is isolating a natural lash and notices a small, pale, oval structure attached near the follicle base. What is the most likely identity of this structure?

  1. A lash mite egg
  2. A sebaceous gland Correct answer.
  3. A Demodex mite
  4. A meibomian gland opening

Explanation

Sebaceous glands (glands of Zeis) are small, pale, lobular structures attached to the upper follicle and are a normal part of the pilosebaceous unit. They should not be confused with meibomian gland openings, which appear as tiny pores along the lid margin, or with parasites, which are not normal anatomy. Recognizing normal structures helps the technician avoid unnecessary alarm or inappropriate treatment.

Question 30Anatomy and Physiology of the Eye and Eyelashes

During a lash extension service, the technician observes that the client's upper eyelid margin has a row of tiny openings just behind the lash line. What is the primary function of the structures that open at these pores?

  1. They secrete mucus that helps tears adhere to the cornea.
  2. They produce aqueous tears that wash away debris.
  3. They secrete an oily substance that coats the tear film and slows evaporation. Correct answer.
  4. They produce melanin that colors the eyelashes.

Explanation

The openings along the lid margin are the orifices of the meibomian glands, which secrete meibum, an oily lipid layer that coats the tear film and reduces evaporation. This lipid layer is essential for tear film stability. Aqueous tears are produced by the lacrimal gland, and mucus is produced by goblet cells in the conjunctiva.

Question 31Sanitation, Disinfection, and Infection Control

Before beginning a lash set, a technician should clean the eyelid and lash area primarily to do which of the following?

  1. Remove oil, makeup, and debris that reduce adhesive hold and carry microbes Correct answer.
  2. Darken the natural lashes for a fuller base
  3. Soften the natural lashes so extensions bond faster
  4. Numb the eyelid so the client stays still

Explanation

Cleansing removes sebum, cosmetic residue, and environmental debris that both weaken adhesive retention and carry microorganisms to the treatment site. A clean, dry lash line is the foundation of every sanitation protocol in lash work.

Question 32Sanitation, Disinfection, and Infection Control

What is the correct classification of a product labeled as a hospital-grade disinfectant suitable for lash implements?

  1. It kills a broad spectrum of pathogens on pre-cleaned hard surfaces Correct answer.
  2. It sterilizes implements by destroying all bacterial spores
  3. It replaces the need for mechanical cleaning before immersion
  4. It is safe to use directly on the client's eyelids

Explanation

Hospital-grade disinfectants are formulated to inactivate a broad range of pathogens on hard, non-porous surfaces, but they require prior cleaning to remove organic soil. They are not sterilants and are not intended for skin contact.

Question 33Sanitation, Disinfection, and Infection Control

A technician uses a single lash extension tweezer on two consecutive clients. Which practice meets standard infection-control expectations?

  1. Wiping the tweezer with a dry tissue between clients
  2. Cleaning and disinfecting the tweezer between clients with an approved product Correct answer.
  3. Spraying the tweezer with adhesive remover between clients
  4. Rinsing the tweezer under warm water between clients

Explanation

Reusable implements must be cleaned to remove residue and then fully immersed or treated with an approved disinfectant at the labeled contact time between clients. Dry wiping, rinsing, or remover spray does not achieve disinfection.

Question 34Sanitation, Disinfection, and Infection Control

Why must a technician avoid touching the adhesive nozzle to the client's natural lashes during application?

  1. It changes the color of the adhesive over time
  2. It causes the extension to bond to the wrong lash
  3. It makes the adhesive cure too slowly to be useful
  4. Contact transfers microbes to the bottle and can seal the nozzle shut Correct answer.

Explanation

Touching the nozzle to lashes or skin introduces client microorganisms into the adhesive container, creating a cross-contamination reservoir, and glue can clog the tip. The nozzle should be kept free of contact with any surface.

Question 35Sanitation, Disinfection, and Infection Control

Which action best describes the purpose of hand washing with soap and water before a lash service?

  1. Mechanically removing transient microorganisms from the hands Correct answer.
  2. Replacing the need for gloves during the service
  3. Sterilizing the hands for the duration of the appointment
  4. Creating a barrier film that repels pathogens

Explanation

Hand washing with soap and friction lifts and rinses away transient flora picked up from the environment and prior contact. It reduces bioburden but does not sterilize the skin or create a lasting barrier.

Question 36Sanitation, Disinfection, and Infection Control

A client arrives with visible crusting, redness, and matted discharge along the lash line. What is the most appropriate technician response?

  1. Apply extensions only to the unaffected eye
  2. Double the adhesive amount to secure the extensions
  3. Cleanse the area aggressively and proceed
  4. Decline the service and refer the client to a physician Correct answer.

Explanation

Signs of possible infection or infestation are contraindications, and lash services should be postponed until a medical professional has evaluated the condition. Proceeding risks worsening the condition and spreading pathogens.

Question 37Sanitation, Disinfection, and Infection Control

Which item in a lash studio is classified as a single-use disposable?

  1. Stainless steel lash comb
  2. Reusable lash palette
  3. Under-eye gel pads used for one client Correct answer.
  4. Ceramic adhesive stone

Explanation

Under-eye pads contact skin and mucus membranes and are designed for one-time use, then discarded. Metal combs, adhesive stones, and palettes are reusable when properly cleaned and disinfected.

Question 38Sanitation, Disinfection, and Infection Control

What is the correct order of steps for reprocessing a reusable metal lash tweezer after a service?

  1. Clean with soap and water, dry, then submerge in disinfectant for the labeled contact time Correct answer.
  2. Wipe with alcohol, then store in a closed drawer
  3. Rinse with water, then place in a UV cabinet for one minute
  4. Submerge in disinfectant, then clean with soap and water

Explanation

Reprocessing always starts with mechanical cleaning to remove organic soil, because soil inactivates disinfectants. After drying, the implement is fully immersed for the contact time stated on the disinfectant label.

Question 39Sanitation, Disinfection, and Infection Control

A technician notices a small cut on their finger before starting a lash appointment. What is the recommended control measure?

  1. Continue barehanded but avoid the cut area
  2. Cover the cut with a waterproof dressing and wear gloves Correct answer.
  3. Apply adhesive over the cut to seal it
  4. Rinse the cut with adhesive remover and proceed

Explanation

Open lesions on the hands are a route for both bloodborne pathogen transmission and wound contamination. A waterproof dressing plus gloves protects the client and the technician during the service.

Question 40Sanitation, Disinfection, and Infection Control

Why is it important to follow the manufacturer's contact time on a disinfectant label rather than a shorter soak?

  1. Kill claims are validated only for the full labeled exposure time Correct answer.
  2. Shorter soaks make the implement easier to dry
  3. Longer soaks always corrode metal implements
  4. Contact time only affects the product's fragrance

Explanation

A disinfectant's efficacy claims are established through testing at a specific concentration and contact time. Shortening the soak leaves pathogens viable even though the tool looks clean.

Question 41Sanitation, Disinfection, and Infection Control

Which practice best prevents cross-contamination from a technician's mobile phone during a lash appointment?

  1. Wipe the phone once weekly with a dry cloth
  2. Answer calls with gloved hands and continue working
  3. Set the phone on the clean lash pillow between clients
  4. Keep the phone away from the treatment area and sanitize hands after touching it Correct answer.

Explanation

Personal devices are high-touch fomites that should stay out of the treatment zone, and hand hygiene is required after any contact. Placing a phone on client linens or handling it with gloved hands spreads contamination.

Question 42Sanitation, Disinfection, and Infection Control

A disinfectant solution was mixed three days ago and stored in an open tray. What is the best action before the next client?

  1. Discard it and prepare a fresh solution according to the label Correct answer.
  2. Add a splash of concentrate to strengthen it
  3. Use it as-is because disinfectants do not expire
  4. Top it off with water to reach the original volume

Explanation

Disinfectant efficacy degrades over time and with evaporation, and dilution or topping off alters the tested concentration. Solutions should be prepared fresh per manufacturer instructions and replaced when spent.

Question 43Sanitation, Disinfection, and Infection Control

What is the primary reason lash technicians should not store adhesive near a heat source or in direct sunlight?

  1. Heat makes the adhesive change to a lighter color
  2. Heat causes the adhesive to become a disinfectant
  3. Heat increases the adhesive's shelf life
  4. Heat degrades the adhesive and can cause premature curing or pressure buildup Correct answer.

Explanation

Cyanoacrylate adhesives are sensitive to heat and moisture; elevated temperatures shorten shelf life and can cause premature polymerization or container pressure. Proper storage protects both product performance and safety.

Question 44Sanitation, Disinfection, and Infection Control

A technician uses the same adhesive stone for several clients without cleaning it. Which risk does this create?

  1. The adhesive cures faster on an unclean stone
  2. The stone loses its ability to hold the adhesive drop
  3. The stone becomes permanently magnetic
  4. The stone becomes a contaminated surface that transfers microbes to fresh drops and tools Correct answer.

Explanation

Any work surface that contacts adhesive drops, tools, or gloved hands accumulates contamination. Stones and palettes must be cleaned and disinfected or covered with a fresh barrier between clients.

Question 45Sanitation, Disinfection, and Infection Control

Which statement correctly distinguishes cleaning from disinfection in a lash studio?

  1. Disinfection is only required for items that contact blood
  2. Cleaning and disinfection are interchangeable terms for the same process
  3. Cleaning removes visible soil, while disinfection reduces pathogens on a cleaned surface Correct answer.
  4. Cleaning kills spores, while disinfection removes visible soil

Explanation

Cleaning is the physical removal of soil and organic matter, and disinfection is the chemical reduction of pathogens on an already cleaned surface. Both steps are required to achieve a safe implement.

Question 46Sanitation, Disinfection, and Infection Control

A client reports a previous reaction of itching and redness after a patch test. What is the appropriate action?

  1. Proceed using the same adhesive on one eye only
  2. Proceed with a smaller amount of adhesive
  3. Proceed but remove the extensions after one hour
  4. Do not proceed with the adhesive and document the reaction Correct answer.

Explanation

A documented allergic or irritant reaction is a contraindication to using that product, and the reaction should be recorded. Reducing quantity or limiting the area does not prevent sensitization or reaction.

Question 47Sanitation, Disinfection, and Infection Control

How should a technician handle linens and towels used during a lash service?

  1. Use a clean set per client and launder soiled linens before reuse Correct answer.
  2. Store used linens with clean ones to save space
  3. Spray them with adhesive remover and reuse
  4. Shake them out and reuse for the next client

Explanation

Linens that contact clients are single-use per client and must be laundered before reuse. Mixing soiled and clean linens or spot-treating with remover does not achieve hygiene.

Question 48Sanitation, Disinfection, and Infection Control

A technician develops a habit of resting used tweezers directly on the bare treatment bed between passes. What is the most accurate description of this practice?

  1. It deposits contaminants on a surface the next client will contact Correct answer.
  2. It protects the tweezers from bending
  3. It keeps the tweezers sterile for the next pass
  4. It has no effect because the bed is covered in paper

Explanation

Used implements carry client flora and must rest on a clean, disinfected or barrier-protected surface, never directly on the bed. Contaminating the treatment surface creates a fomite the next client contacts.

Question 49Sanitation, Disinfection, and Infection Control

Which of the following is the most reliable indicator that a reusable implement has been properly disinfected?

  1. It was stored in a closed case overnight
  2. It was wiped with an alcohol pad until it felt dry
  3. It looks shiny and has no visible residue
  4. It was cleaned, immersed in an approved disinfectant for the full labeled contact time, and documented Correct answer.

Explanation

Visual cleanliness is not proof of microbial reduction; only adherence to the cleaned-then-disinfected protocol with the labeled contact time, plus a record, demonstrates the process was performed.

Question 50Sanitation, Disinfection, and Infection Control

A technician is choosing between a low-level and a hospital-grade disinfectant for lash tweezers. Which reasoning is sound?

  1. The choice depends only on the price of the product
  2. Low-level is sufficient because tweezers only touch hair
  3. Either is acceptable because both are labeled disinfectants
  4. Hospital-grade is appropriate because tweezers contact skin and lashes and may carry pathogens Correct answer.

Explanation

Reusable implements that contact skin and mucous membranes require a disinfectant with broad-spectrum efficacy at the labeled dilution and contact time. Low-level products may not cover the pathogens of concern.
